ADSP-218x DSP Loader/Splitter
ADSP-218x DSP Splitter Guide
Use the splitter (
elfspl21.exe
) to process an executable file to produce a
non-bootable, PROM-image file. In most cases, developers working with
ADSP-21xx DSPs use the loader instead of the splitter.
This section contains the following information on the splitter.
• “Using Splitter” on page 5-15
Describes how to use the splitter from a command line.
• “ADSP-218x Splitter Command-Line Reference” on page 5-16
Summarizes and describes the splitter command-line switches.
Using Splitter
!
You must run the splitter (PROM splitter) from a command line.
You cannot generate a non-bootable PROM file from within the
Vi+ environment. To automate the process, specify the
splitter command-line within Vi+ from the
Post Build
page of the Project Options dialog box.
The ADSP-218x splitter generates images for external
PMOVLAY
(1 and 2)
and
DMOVLAY
(1 and 2) memory pages. If you use the splitter to produce
ROM images (for example, the ADSP-2181DSP’s program memory pages
1 and 2), the generated code must target ROM. Define the appropriate
ROM segments in the
.LDF
file.
Splitter options control how the splitter processes executable files, letting
you select features such as memory type and file format.
